ABSTRACT

Objective:

To investigate the clinical significance of MRI dynamic enhancement in defining the upper edge of adenocarcinoma of esophagogastric junction.

Methods:

The clinical data of 73 patients with adenocarcinoma on the esophagogastric junction operated from Jul 2018 to Aug 2019 in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively analyzed. All patients underwent MRI examination within one week before surgery. First, the T 2WI, diffusion-weighted imaging and dynamic enhanced images of each patient were carefully observed to define the tumor location, size, shape, signal and enhancement mode, then the distances between the upper edge of the tumor and the cardiac incisure on MRI dynamic enhancement were measured independently, and compared with the measured distance in surgical fresh specimens.

Results:

The mean location of tumor upper edge measured in MRI of 73 patients was (1.75±1.98)cm, while measured in the surgical specimen was (1.72±1.97)cm. There was no significant difference between the two groups ( t=0.572, P=0.569). The intraclass correlation efficient between the two groups was excellent (ICC=0.974, 95% CI 0.959-0.984, P<0.01).

Conclusion:

The measurement result of tumor upper edge in MRI is basically consistent with that of surgical specimens. MRI can be used to locate the tumor upper edge for adenocarcinoma of esophagogastric junction before operation.
